Ingredients

Scale
  • 1 (14.4 ounce) package instant vanilla pudding mix
  • 3 cups cold milk
  • 1 (8 ounce) container frozen whipped topping, thawed
  • 1 (14.4 ounce) box graham crackers, whole sheets
  • 1 (5.9 ounce) package instant chocolate pudding mix
  • 2 cups cold milk (for chocolate layer)
  • 1 cup semi-sweet chocolate chips
  • 1/2 cup heavy cream

Instructions

  1. Prepare the vanilla pudding: Whisk the instant vanilla pudding mix with 3 cups of cold milk until thick, about 2 minutes. Gently fold in the thawed whipped topping until just combined.
  2. Assemble the first layer: Arrange a single layer of graham cracker sheets in the bottom of a 9×13 inch baking dish. You may need to break some crackers to fit the edges.
  3. Add the first filling layer: Spread half of the vanilla pudding mixture evenly over the graham crackers.
  4. Add the second cracker layer: Place another layer of graham crackers over the pudding.
  5. Add the second filling layer: Spread the remaining half of the vanilla pudding mixture over the second cracker layer. Top with a final layer of graham crackers.
  6. Chill: Cover the dish and refrigerate for at least 2 hours, or until the crackers soften slightly.
  7. Prepare the chocolate glaze: In a small saucepan, heat the heavy cream until it just begins to simmer. Remove from heat and pour over the chocolate chips in a heat-safe bowl. Let stand for 5 minutes, then whisk until smooth.
  8. Prepare the chocolate pudding: In a separate bowl, whisk the instant chocolate pudding mix with 2 cups of cold milk until thick.
  9. Top the cake: Spread the prepared chocolate pudding evenly over the top graham cracker layer. Then, pour the warm chocolate glaze over the pudding layer and spread to cover completely.
  10. Final chill: Refrigerate the Eclair Cake for at least 4 hours, or preferably overnight, before slicing and serving.

Notes

  • For the best texture, allow the cake to chill overnight. This lets the graham crackers fully absorb moisture from the pudding.
  • You can substitute the graham crackers with vanilla wafers for a different texture.
  • If you prefer a firmer chocolate topping, use a standard chocolate frosting recipe instead of the ganache glaze.
